This book offers a holistic view of Julio Boltvinik's vast and important work on poverty conceptualisation and measurement. While well known to Spanish-speaking audiences, this volume brings these works together to offer access for English-speaking audiences for the first time. The book provides the foundations, application and empirical examples of Boltvinik's Integrated Poverty Measurement Method, which could potentially transform poverty narratives globally as it has done in Mexico. Deeply critical of available poverty approaches, it provides a challenging and radically new way of conceiving and measuring poverty, offering the only multidimensional poverty measurement method which includes time poverty and allows all Aggregate Poverty Measures to be fully calculated.
